The U.S. Secret Service says a man who opened fire near a White House security checkpoint is dead. It was the third incidence of gunfire in the vicinity of President Donald Trump in the past month. The agency says in a statement Saturday that a preliminary investigation found the man was near 17th Street and Pennsylvania Avenue when he pulled a weapon from his bag and began firing. Its officers returned fire. The suspect died later at a hospital. A bystander also was shot. Trump was at the White House at the time. Secret Service said he was not “impacted.”

Authorities are bracing for the possibility that a damaged chemical tank at a facility in Southern California could leak or explode. An evacuation order has continued into the Memorial Day weekend for 40,000 residents of Garden Grove and several surrounding communities with no timeline on when they can return. No injuries were reported after the pressurized tank began overheating Thursday. Firefighters hope to find a way to cool off the chemical inside the tank so it won’t leak or explode. Experts say a leak would be much better than an explosion. Gov. Gavin Newsom has declared a state of emergency in Orange County. Several shelters remain open, including at three schools.
